実験手順

βAET was synthesized using 3β,17β- diacetoxyandrost-5-ene as a starting material. Chromic oxide oxidation of 3β,17β-diacetoxyandrost-5-ene in glacial acetic acid by the method of Butenandt (op. cit.) gave 3β,17β-diacetoxyandrost-5-en-7-one, (III), the intermediate for preparation of (I). Aluminum isopropoxide reduction of (III) in isopropanol by the method of Butenandt gave (I).
